FilteredQuery has been removed. Instead, you can construct a BooleanQuery with
one MUST clause for the query, and one FILTER clause for the filter.
## PhraseQuery and BooleanQuery made immutable (LUCENE-6531 LUCENE-6570)
PhraseQuery and BooleanQuery are now immutable and have a builder API to help
construct them. For instance a BooleanQuery that used to be constructed like
this:
BooleanQuery bq = new BooleanQuery();
bq.add(q1, Occur.SHOULD);
bq.add(q2, Occur.SHOULD);
bq.add(q3, Occur.MUST);
bq.setMinimumNumberShouldMatch(1);
can now be constructed this way using its builder:
BooleanQuery bq = new BooleanQuery.Builder()
.add(q1, Occur.SHOULD)
.add(q2, Occur.SHOULD)
.add(q3, Occur.SHOULD)
.setMinimumNumberShouldMatch(1)
.build();
